Turtle and Observer Command

grab number [list of commands]

Caller instructs turtles with who number(s) number(s) to execute [list of commands]. The who number of the turtles being grabbed are stored in partner, if there is one, or partners, if there are many. A turtle cannot grab itself.

Examples:
grab one-of-turtles-here [setc red setc-of partner blue]
This turns the caller red and the grabbed turtle blue. If there are no other turtles on the caller's patch, the [list of commands] does not get executed and no turtles change color.
